Title: Control device for engine
Inventor: YOSHIKAWA TAKASHI
IPC: F02P5/15
Filed: 1994-12-06
Abstract: PURPOSE: To prevent required ignition voltage of a fuel stop cylinder from exceeding withstand voltage by so selecting normal ignition timing for a cylinder that ignition plug discharge resistance for other cylinder becomes small. CONSTITUTION: In ignition plugs 19 disposed at respective cylinders, with two cylinders in mutual phase difference of crank angle 360 deg. being a pair, each cylinder is connected to a respective ignition coil 20 and so an ignition signal is outputted in each ignition timing. And thus, in two ignition plugs 19 connected to single ignition coil 20, the discharge at a cylinder is made deviated from normal ignition timing by crank angle 360 deg., besides normal ignition timing at a cylinder disposed with each ignition plug 19. In an engine control unit 23, when fuel supply is stopped due to traction control, ignition pulse outputting to an ignition coil to which an ignition plug 19 at the fuel-stopped cylinder is connected, is stopped.

Title: Power transmitting device
Inventor: ITO SADAO
IPC: B60N2/07
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent an elastic body from being deformed into a different shape at its deflected part by integrally forming the elastic body on a nut such that it covers the whole surface of the nut and is put into tightly contact with the nut in a power transmitting device for transmitting the rotational movement of a driving source as the linear movement of a driven member. SOLUTION: Since a nut 62 is fixed to a lower rail 1 in a power seat device of a car, if a motor 5 is driven, a screw shaft 61 is relatively moved with an upper rail 2 and thus a seat position is adjusted to-and-fro. When a seat reaches a front end, one side wall 63b1 opposite to the peripheral wall 63b of a holder 63 is put into contact with a stopper 64 to control a relative motion between a screw shaft 61 and the nut member 62. The part of an elastic body abutting on the wall of cushion rubber is deflected but is prevented from being deformed into a different shape owing to this deflection because the part is put into tightly contact with the whole surface of the nut member 62 and thus is hard to come off.

Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To generate a system clock controlling an expanded video signal among a plurality of display rates by executing alternate division sequence for a divider coupled with a clock signal source and dividing a clock signal. SOLUTION: In order to convert mutually video signals sent by the two kinds of MPEG compression forms whose frame rate is slightly different and to display them, it is desired that synchronizing signals are selectively outputted at a slightly different rate. A display clock oscillator VCXO 401 is indirectly phase locked to a system clock of 27.00MHz with a system recovery circuit 26 and a divider circuit 403. A programmable divider 405 receives a frequency twice that of a horizontal synchronizing signal and sets alternately a divisor N1 or N2 according to a predetermined sequence and generates a synchronizing signal through division.  Thus, the divisor is a mean value of a counter output as a result of module effectively and alternately and a vertical synchronizing signal and a frame synchronizing signal whose frequency is not an integer are obtained from an oscillator with an integer oscillating frequency.

Title: Refrigeration cycle
Inventor: SAKAI TAKESHI
IPC: F25B1/00
Filed: 1993-12-27
Abstract: PURPOSE:To increase the amount of refrigerant circulation and ensure a required freezing capability by employing as a refrigerant an HFC refrigerant that has a higher boiling point than HCFC or has a greater gas ratio volume and setting standard operation frequency of a compressor to be 1, 1 to 2 times that upon the use of the HCFC. CONSTITUTION:Use of HFC, as a refrigerant, that has a higher boiling point or a greater gas ratio volume than HCFC(dichlorofluoromethane) or CFC (chlorofluorocarbon) ensures expansion of a standard operation frequency region of a compressor because of the temperature rise of the compressor being smaller. For this, HFC is used as a refrigerant to operate the compressor with its operation frequency set to be 1.1 to 2 times than upon the use of a conventional refrigerant(HCFC). Hereby, the identical freezing capability as the conventional one is ensured and the load to replace a refrigerant is reduced only with reduced alteration of the structure.
